Harnessing the Power of Myth

Every organization has its user myths: a set of beliefs about the users knowledge,
experience and needs. Typical myths could be:

Users will learn about the drag & drop capability from training

Users know how to calculate the slope and intercept for a line

The user is the same person who installed the product

Myths Influence Design

In themselves, user myths arent inherently good or evil. The issue is
that they are always present and they influence the design of the product.

For example, an assumption that the user was the same person who installed
the product might lead to a decision to educate the user on product features
during the installation process.

The Perils of User Myths

Problems can arise when a product is developed around subconscious, unsubstantiated,
or conflicting user myths. Myths in this form often contribute to the "opinion
wars" that form between members of the development team and can result
in products that dont meet users real needs.

Make Myths Explicit

The first step toward harnessing the power of user myths is simply to recognize
what the current user myths are. This can be done simply and inexpensively.
Here are some common ways to uncover your teams myths:

Brainstorm. Ask people involved in development to describe their assumptions
about users.

Look for evidence in the product itself. For example, if the product
works like a spreadsheet, there may be an underlying myth that the users know
spreadsheets.

Caveat: Dont try to prove or disprove myths at this stage. If people
have opposite impressions, simply record both versions of the myth.

Gather Evidence

Once youve collected some user myths, you can look for data to confirm
or disprove them:

By usability testing

In conversations with users

Through surveys

From people who have direct contact with users (training, tech support)

Sometimes the evidence is contradictory  if users truly have conflicting
needs, you might consider giving the user a choice or perhaps dividing up the
product for different users, even into multiple separate products. (Intuit,
the makers of Quicken, have done this for their products very successfully.)

Find Any Surprises?

If any user myth turns out to be false, review the current product design
to see if it was influenced by this assumption. If so, change the design.

Build a Shared Vision

As you gather evidence, publicize what youve learned. This can be as
simple as a bullet list you e-mail to co-workers, or as formal as a published
user profile. Refining your "user myths" into a shared realistic
vision of users and their work results in fewer arguments and a more usable
product.
